UNITED STATES DANIEL W. ROM, OF WAUWATOSA, WISCONSIN.

STOPIPER.

Application filed June 13,

This invention relates particularly to a stopper or closure for wash bowls, sinks and the like, and has as an object to provide a stopper of this character with a removable strainer.

Another object of this invention resides in the provision ot a stopper oi? the character described having a cup shaped receptacle or body member in which a strainer is detachably positioned and a stopper proper, guided for movement into and out of engagement with its seat by a guide carried by the detachable strainer.

Another objectof this invention resides in the provision of a closure of the character described in which the stopper is actuated to either position by turning the same.

ith the above and other bjects in view which will appear as the description proceeds, my invention resides in the novel construction, combination and arrangement o't parts substantially as hereinafter described and more particularly defined by the appended claims, it being understood that such changes in the precise embodiment of the herein disclosed invention may be made as come within the scope of the claims.

In the accompanying drawing, I have illustrated one complete example oi? the physical embodiment of my invention eonstrueted according to the best mode I have so far devised for the practical application of the principles thereof, and in which:

Figure is a transverse, sectional view through a. wash bow]. closure embodying my invention, parts thereof being in elevation;

Figure 2 is a. cross sectional view, taken through Figure 1 on the plane of the line 22;

Figure 3 is an enlarged, detail View illustrating the guide in which the stem of the stopper is positioned; and

Figure 4- is a top plan View oi: the stopper or plug.

Referring now more particularly to the accompanying drawing in which like numerals designate like parts throughout the several views. 5 designates the bottom of a wash bowl, sink, or the like. which is provided with an aperture 6 formed, in an annular flange 7 offset with respect to the sink bottom to term an annular recess 8. Positioned within the aperture is a cup shaped receptacle or body member 9 having a flange 1928. Serial No. 285,044.

10 directed laterally from its upper periphery to be supported within the annular recess 8 spaced from the bottom of the recess by a gasket 11. The outer surface of the receptacle 9 outwardly of the flange 7 is provided with a screw thread 12 to receive retaining nut 13 between the upper face of which and the bottom of the flange 7 a second gasket 14: and a washer 15 are impinged to secure the receptacle 8 to the sink bottom with its upper flange 10 substantially flush therewith.

The bottom 16 of the receptacle is apertured, as at 17, to permit the contents of the sink or nashbowl to pass outwardly thereof when a stopper 18 is in its open position il lustra ted in dotted lines in Figure 1. The stopper l8 substantially disc shaped having its outer periphery tapered inwardly, as at 19, to engage a seat 20 formed at the adjacent periphery of the receptacle 9 to close the opening 17.

l-lemovably positioned within the receptacle S is a strainer member 91 having an upwardly directed flange 22 which engages the inner wall of the receptacle. The strainer has a central. aperature and a. downwardly directed annular flange 21 in which the lower end of a tubular guide 2 is suitably secured to provide m ans for guiding the movement of the stopper 18.

The stopper has a central downwardly extended stem 24- slidably positioned in the tubular guide 23 and carries a pin 25 which is operable within a spiral groove 26 formed. in the tubular guide 23. The upper face of the stopper 18 is provided with a pair of arcuate shaped recesses 97 on each side of its axis to form. a linger engaging rib 28 by which the stopper may be rotated to cause the stem to move to its open or closed position, the pin 25 riding up in the spiral groove, as will be readily apparent, to open the stopper. A downwardly projected recess or notch 29 is provided at the upper end of the spiral groove for the pin 25 to detachably retain the stopper in its full open position.

From the foregoing description, taken in connection with the accompanying drawing, it will be readily apparent to those skilled in the art to which an invention of the character described appertains, that I provide a closure for washbowls, sinks, and the like in which the strainer and the stopper are removable as-aunit to permit ready cleaning of the parts.

hat I claim as my invention is:

1. A device of the character described comprising a cup shaped receptacle having an aperture in its bottom, a stopper engageable with the receptacle to close the aperture, a strainer removably positioned Within the re-- ceptacle, a guide carried by the strainer having a spiral groove'therein, a stem extended from the stopper and movable in, theguide, and apin carriedby the stem and positioned Within the spiral groove whereby rotation of the stopper actuatjes the same to either open or closed position.

2. A device of the character. describedicomprising a cup shaped receptacle having an aperture in its'bottom, a stopper engageable with the receptacle to close the aperture, a st 'ainer removably positioned Within the receptacle a guide carried by the strainer having a spiral groove therein, a stem extended from the stopper and movable in the guide, a pin carried by the stem and p0- sitioned within the spiral groove whereby rotation of the stopper actuates the same to either openor closed position,.and means for retaining the stopper in its full open position.

In. testimony whereofi I have hereunto atfixed my signature.
